Question

In AWXY, WY is extended through point Y to point Z, m_YW X = (2x + 12),
mZWXY = (2x + 5)', and mZXYZ = (7x - 1)º. What is the value of x?

Answer 1

Answer:

Sum of two interior angles=exterior angle

$\\ \sf\longmapsto 2x+12+2x+5=7x-1$

$\\ \sf\longmapsto 4x+17=7x-1$

$\\ \sf\longmapsto 3x=18$

$\\ \sf\longmapsto x=6$

Done!
